On Friday’s episode of “Morning Joe,” host Joe Scarborough pointed out that there is no religious grounding for Ben Carson’s theory that the Egyptian pyramids were built by the biblical patriarch Joseph for grain storage.

“I spent about three or four days a week reading the Bible in church, and was literally raised in the Southern Baptist church. And I don’t believe his theory. It’s crazy!” Scarborough said. “In my 50 years in church I’ve never heard this theory.”

Scarborough and guest Mark Halperin, a senior editor at Bloomberg Politics, questioned whether Carson's "personal theory" could sink his support among Republican presidential voters. The MSNBC host framed the pyramid comments as another "quirky" interlude in Carson's "inconsistent" campaign.

“The Bible, which we Christians say is one of the most important historical documents of ancient times, never mentions things like that,” Scarborough said.

Carson has defended himself by saying “secular progressives” are trying to discount his faith-based explanation for the pyramids.

"Some people believe in the Bible, like I do, and don't find that to be silly at all,” Carson told reporters in Miami on Thursday.
